First 'Rauisuchian' archosaur (Pseudosuchia, Loricata) for the Middle Triassic Santacruzodon assemblage zone (Santa Maria Supersequence), Rio Grande do Sul State, Brazil. [PDF]
PLoS ONE, 2015 The 'Rauisuchia' are a group of Triassic pseudosuchian archosaurs that displayed a near worldwide distribution. In Brazil, their fossils are found only in the Santa Maria Formation (Paraná Basin) of the Rio Grande do Sul State, specifically in the Middle

Growth curve of Aetosauroides scagliai Casamiquela 1960 (Pseudosuchia: Aetosauria) inferred from osteoderm histology [PDF]
Geological Society, London, Special Publications, 2013 Recent paleohistological studies on paramedian osteoderms of aetosaurs revealed the presence of growth lines (lines of arrested growth or LAG’s) and a minimal or nonexistent secondary remodelling in the bone matrix of these elements.

Osteology of the Late Triassic aetosaur Scutarx deltatylus (Archosauria: Pseudosuchia)
PeerJ, 2016 Aetosaurs are some of the most common fossils collected from the Upper Triassic Chinle Formation of Arizona, especially at the Petrified Forest National Park.

Reassessment of the enigmatic “Prestosuchus” loricatus (Archosauria: Pseudosuchia) from the Middle‐Late Triassic of southern Brazil [PDF]
The Anatomical Record, Volume 307, Issue 4, Page 974-1000, April 2024.Abstract Our knowledge of the diversity and evolution of South American Triassic pseudosuchians has greatly improved in the past 15 years, due to new discoveries, but also to the revision of several historically important specimens. One of the earliest descriptions of pseudosuchians from the Triassic of Brazil stems from the classic work of Huene from ...

Dermal armour histology of aetosaurs (Archosauria: Pseudosuchia), from the Upper Triassic of Argentina and Brazil [PDF]
Lethaia, 2010 One of the most striking features documented in aetosaurs is the presence of an extensive bony armour composed of several osteoderms. Here, we analyse the bone microstructure of these elements in some South American Aetosaurinae aetosaurs, including ...

(Archosauria: Pseudosuchia) from Western North America
The Anatomical Record, 2020 ABSTRACTPoposaurus gracilis is a bipedal pseudosuchian archosaur that has been poorly understood since the discovery of the holotype fragmentary partial postcranial skeleton in 1915. Poposaurus. gracilis is a member of Poposauroidea, an unusually morphologically divergent clade of pseudosuchians containing taxa that are bipedal, quadrupedal, toothed ...

Hindlimb functional morphology and locomotor biomechanics of the small Late Triassic pseudosuchian reptile Gracilisuchus stipanicicorum (Archosauria: Gracilisuchidae). [PDF]
J AnatA three‐dimensional biomechanical model of the musculoskeletal system is used to analyse the potential locomotor functions of the small (~1 kg) Late Triassic archosaurian reptile Gracilisuchus stipanicicorum. The study finds that, potentially like the ancestral archosaur, this taxon was probably quadrupedal, plantigrade and neither strongly sprawling ...

Journal of Vertebrate Paleontology, 2017 The evolution of the braincase and brain of early pseudosuchians through to the earliest crocodylomorphs is poorly understood given the paucity of specimens, lack of well-preserved material, and lack of consensus on the phylogenetic relationships of the major clades of Pseudosuchia.

, 2019 Recently discovered specimens of "Rauisuchia" have boosted interest in this enigmatic group of pseudosuchians, because they provide crucial information on major patterns and processes in continental Triassic archosaur evolution. Here we analyze limb bone

Pseudosuchian thermometabolism: A review of the past two decades. [PDF]
Anat Rec (Hoboken)Abstract Pseudosuchia, one of the two main clades of Archosauria, is today only represented by some 20 extant species, the crocodilians, representing only a fraction of its extinct diversity. Extant crocodilians are ectotherms but present morphological and anatomical features usually associated with endothermy.
